Square pie / Waffle chart
Data on women in information technology using square pie. A square is divided into 10x10 fields, and for each number, as many fields are filled in as there are percent. Consequently, the numbers remain readable by simply counting the number of fields covered by one colour. Taking a hint from squarified treemaps, the areas should also be as square as possible for better comparability.<br />The square pie chart is for completely flat data that adds up to 100%, whereas the treemap shows structured data: a hierarchy. They may end up looking the same, but the meaning is not.
